Accepting a larger key payload truncates the\nrecorded length and can make later users interpret the payload using\ninconsistent bounds.\n\nReject oversized preparsed payloads before allocating or copying them.\nThis keeps key-\u003edatalen consistent with the stored data for both inline\nand separately allocated idmap payloads.","modified":"2026-09-27T05:34:32Z","published":"2026-09-24T17:17:11Z","upstream":["CVE-2026-93785"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93785"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103994.json"}}],"schema_version":"1.9.0"}
